A portfolio of shipped product work demonstrates this best. * Experience creating and maintaining design systems, with deep care for layout, motion, affordances, color and visual polish * Self-starter with an end-to-end owner's mindset. Bias to ship and polish through iteration. You move from ambiguous problem to testable prototype quickly, and you can fluently use AI-native tooling (Claude, Cursor, etc) to compress the iteration cycle. * Expertise in modern front-end technologies, especially Typescript, CSS, React, and component-driven architectures. * Strong communicator who builds shared understanding across scientists, designers, and engineers. * Typically 5+ years of relevant work, though depth and quality of what you've shipped matter more than years on a CV. Nice to have * Experience designing expert tooling for practitioner audiences: surfaces where interface complexity is earned by the depth of the underlying domain. Think Houdini, Hex, Final Cut Pro, Benchling, or any modern IDE. * Experience designing data-dense interfaces. Charts, tables, and quantitative displays where the encoding choice matters. You don't need to be a statistician, but you have opinions about how to make complex information legible. * Experience with application-level frontend concerns like state management, data fetching, and API integration, so you can take features further into production on your own * Background in biotech, research tools, or developer tooling. ## Description At Cradle, we're building a platform that lets biologists use machine learning to design and optimize proteins, faster and at scale. Our users are scientists running complex, mission-critical workflows: designing experiments, preparing and reviewing training data, configuring and running ML models, and interpreting results across multiple cycles of iteration. The product surface is unusually rich and fast-moving. Biological sequence data, experiment tracking, model configuration, data preparation pipelines, and dense result exploration views all sit in a single platform, and the underlying ML capabilities keep evolving. The interfaces around them have to evolve just as quickly, in the hands of domain experts who hold a high bar for clarity and craft., This is a product role with leverage: you'll work fluidly across UX research, visual design, and frontend engineering, picking up wherever the most useful work is, prototyping in code when a static design can't capture what an interaction needs to feel like, and shipping with our frontend engineers when something is ready to scale into production. You will join experienced designers, frontend engineers and UX researchers who care deeply about the craft of the product. You bring a point of view on how features should behave, contributing to how the team works, and pull work towards concrete, shippable decisions while retaining a high quality bar. You don't need a biology background. You do need to find complex, data-dense product surfaces genuinely interesting and care about getting them right. ## Related Videos - [Learn Enough Design to Be Dangerous](https://www.wearedevelopers.com/videos/577-learn-enough-design-to-be-dangerous) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [A Brief History of Data Storage](https://www.wearedevelopers.com/videos/974-a-brief-history-of-data-storage) - [TypeScript Features That Changed the Game](https://www.wearedevelopers.com/videos/100061-typescript-features-that-changed-the-game) - [WeAreDevelopers LIVE - CSS is DOOMed](https://www.wearedevelopers.com/videos/1851-wearedevelopers-live-css-is-doomed) ## Related Articles - [Dev Digest 133 - Back to Front](https://www.wearedevelopers.com/magazine/474-dev-digest-133-back-to-front) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Dev Digest 129 - Now that's what I call private data!](https://www.wearedevelopers.com/magazine/468-dev-digest-129-now-that-s-what-i-call-private-data)
